验证容器隔离链路，`Dockerfile.scanners` 提供带 `bandit`、`ruff`、`detect-secrets` 的镜像，用于实际离线 scanner 执行。SQLite 保存 task、输入、sandbox run、Filter 决策、finding、监控和报告，并通过 `ReviewStore` 保留 SQL 后端扩展点。报告输出 JSON/Markdown，高置信进入 findings，中置信进入 warnings，低置信进入人工复核；同一文件、行号、类别只保留最高优先级项。所有 diff、stdout、stderr、Filter reason 和 finding evidence 在落库前脱敏，并记录耗时、工具调用、拦截、异常、严重级别分布和去重数量，便于后续回放和审计。 diff --git

生命周期、事务处理和 SQL 插值。 +- `missing_tests`：源码变更缺少测试变更。 +- `duplicate_findings`：重复问题模式，用于去重测试。 +- `sandbox_failure`：沙箱失败被记录，任务不崩溃。 +- `secret_redaction`：报告和数据库中脱敏 secret。 +- `sandbox_timeout`：沙箱超时被记录，任务不崩溃。 +- `sandbox_large_output`：沙箱输出被截断并记录。 +- `sandbox_secret_output`：沙箱 stdout/stderr 中的 secret 被脱敏。 +- `hidden_like_multiline`：多行 shell=True、SQL 变量拼接后 execute、保存但未观察的 task。 +- `ast_taint`：函数参数/request taint 流向 shell 和 SQL sink。 +- `ignore_rule`：`# cr-agent: ignore=` 忽略规则样本。 +- `entropy_secret`：高熵字面量 secret 脱敏样本。 +- `external_scanner`：外部 scanner finding 合并入报告和数据库的样本。 +- `resource_lifecycle_closed`：有 finally close 的资源生命周期样本，用于降误报。 +- `secret_redaction_extended`：AWS、Slack、JWT 和通用 token 脱敏样本。 + +# Skills Code Review Agent + +This example demonstrates an automatic code review agent built from a reusable Skill, sandbox execution, Filter governance, SQLite persistence, structured findings, and monitoring audit output. + +## What It Covers + +- `skills/code-review/SKILL.md` with rule docs and sandbox scripts. +- Unified diff, PR patch, repo path, file-list, stdin, and fixture input parsing. +- Fake/offline mode for CI and no-key development. +- Container/Cube-ready sandbox adapter boundary, with local mode only as explicit fallback. +- SQLite records for task, diff, sandbox run, filter decision, finding, monitoring summary, and final report. +- Secret redaction before report and database writes. +- Deduped findings plus warnings and `needs_human_review`. +- Review rules cover seven categories: security risks, async errors, resource leaks, test gaps, secret leaks, database transactions, and database connection lifecycle, with Python AST/taint assistance. +- Sandbox-side scanner aggregation runs offline bandit, ruff, and detect-secrets by default; network-backed semgrep auto scanning is opt-in and must pass Filter. +- `rules.json` and `filter_policy.json` provide rule configuration, Filter policy-as-code, and workspace path allowlists. +- `# cr-agent: ignore=` suppresses a specific rule and records ignored counts. +- `agent/native_agent.py` exposes the complete review pipeline as a `FunctionTool` for `LlmAgent`. +- `agent/native_filter.py` exposes the same governance policy as a tRPC-Agent `BaseFilter` adapter. +- `ReviewStore.from_url()` supports `sqlite:///...` and keeps explicit Postgres/MySQL extension points. +- Reports include confidence thresholds, dedupe counts, Filter summaries, sandbox summaries, monitoring metrics, and actionable recommendations. + +## Run + +From the repository root: + +```bash +python
